L.B. White Volt 1.5 Electric Greenhouse Heater (120V, 1500W)

L.B. White Volt 1.5 Electric Greenhouse Heater (120V, 1500W)

The L.B. White Volt 1.5 is a 120V, 1,500-watt electric greenhouse heater built to run continuously for up to 10 years without a break. At $390, it's the most accessible heater in the L.B. White Volt lineup — plugging into any standard household outlet with no special wiring required. Its 116 CFM industrial fan motor circulates warm air throughout the entire greenhouse rather than just warming a small personal space like a typical household space heater.

What Are the Key Specs of the L.B. White Volt 1.5?

• Voltage: 120V
• Wattage: 1,500W
• Fan output: 116 CFM
• Plug type: Standard 120V household outlet (no special wiring needed)
• Rated lifespan: Built for 10 years of continuous operation
• Overheat protection: Auto shut-off at 104°F
• Certifications: UL approved
• Operation: Combustion-free, no fumes or odors

Does the Volt 1.5 Require Special Wiring?

No — this is the Volt 1.5's biggest practical advantage over the rest of the lineup. It runs on standard 120V power and plugs into any regular household outlet. No electrician, no dedicated circuit, no NEMA adapter required. If you have a standard outlet in or near your greenhouse, you can use the Volt 1.5 immediately out of the box.

How Is the Volt 1.5 Different from a Regular Space Heater?

Most household space heaters are designed to warm a small personal area — a desk, a corner of a room, or a small office. The Volt 1.5 is engineered differently: its 116 CFM industrial fan motor actively circulates warm air throughout the entire greenhouse, raising the ambient temperature of the whole space rather than creating a localized warm zone. This makes it effective for small to medium-sized greenhouses where consistent, even heat distribution matters for plant health.

How Does the Volt 1.5 Compare to the Volt 3 and Volt 6?

The L.B. White Volt lineup offers three heaters at different power levels:

• Volt 1.5 — $390 — 120V, 1,500W, standard outlet, best for smaller greenhouses
• Volt 3 — $547 — 240V, 12.5A, NEMA 6-15P plug, twice the heat output of the Volt 1.5
• Volt 6 — $866 — 240V, 25A, dryer outlet (NEMA 14-30P/14-50P), highest output for large greenhouses

If you don't have a 240V outlet near your greenhouse and don't want to hire an electrician, the Volt 1.5 is the right starting point. If you need more heat output and have a 240V circuit available, step up to the Volt 3 or Volt 6.

Is the Volt 1.5 Safe for Continuous Greenhouse Use?

Yes — the Volt 1.5 is rated for non-stop, continuous operation and is built to last 10 years under those conditions. Safety features include automatic overheat protection at 104°F, a high-quality sealed motor, and powder-coated steel housing that holds up in the humid conditions typical of greenhouse environments. It operates without combustion — no fuel spills, no carbon monoxide risk, and no odors.
